CARHHEATER.

ESPECFCAIIN forming part of Letters Patent No. 384,599, dated June 19, 188Q.

Serial No. 253,414. (No model.)

T r1/ZZ whom 'it rim/y concern:

Be it known that l, Emmen Aivhu'nws, a citizen of the United States, residing at Pottsville, in the county of Schuylkill and State oi" Pennsylvania, have invented certain new and usei'ul Improvements in Car-Heaters; and I do hereby declare the following to be a i'ull,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to means for heating passenger railway-cars, and has for its object the construction of a device for circulating hot water through system or" pipes and footwarniers and returning the cooled water to the boiler to be reheated.

iillany ot' the most serious results of railroadcollisions, dei-ailment of cars, and other similar accidents are produced by the cars being set on lire from the heating` apparatus. It is my purpose to provide a car-heater in which no tire shall be kept up while the train is in motion making a trip or run.

Tae invention will be hereinafter described, and particularly pointed out in the claims.

in the accompanying drawings, which form a part of this specification, Figure 1 is a per` spective of the heater with a portion of the outer case broken away; Fig. 2, a like view of the gearing for propelling a friction-disk. Figs.

3, 4, and 5 are details ofthe friction-heater, and Fig. (i is a perspective ofthe interior of a car with my improved heater applied,

Reference being` had to the drawings and the letters marked thereon, A represents the circulating-reservoir, which consists of anl upper section or chamber, u, through which the lire tube or tubes b pass, and is separated from the lower cl1ainber,c,by two horizontal plates,l c, between which is formed an intermediate chamber, j'. The upper chamber, a, andthe lower chamber, c, communicate through a passage, l/,and the upper and intermediate chambers communicate through a pipe, it, which extends to nearly the upper end of said chamber e and passes through the upper horizontal plate, d.

The reservoir being constructed in separate sections, each section maybe cleaned independently of the others, and worn portions of one section may be replaced without detaching or disturbing the others, and by the construction shown the hottest water is delivered to the system of heatingpipes in the car, while the coolest water is delivered in the lower portion 5 5 of the reservoir,where the water is at its lowest temperature.

Nithin the lower chamber, c, is a iire-pot or furnace, i, provided with a door, Zt, and is surrounded on its sides and top by water, which 6o is supplied through pipes m.

Bis the hot-water-conducting pipe, which communicates with theintermediate chamber,

f, and extends out through any desired portion of a car, forms a return-bend at a, and communicates with a series of enlarged chambers, C, which are placed between or under the seats of the car,and constitute foot-warmers.

The chamber C may be placed on both sides of the car, as shown in Fig. (i, and extend from 7o both sides of the circulating-reservoir. From the chamber G, next to the reservoir A, connection is made with the lower chamber, c, of said reservoir by means of a pipe, o.

The chambers C should be raised from the iloor of the car about one-half of an inch to admit of a circulation of air under them.

To provide for keeping up the circulation of the water in the heating system, I have provided an extension, D, to the lower part ot' the 8o circulating-reservoir A, which is in communication with the chamber c,and is provided with a passage, p, through which the water circulates.

On the upper side of the extension D is S5 formed a seat, q, upon which rests a disk, r, which is provided with a peripheral groove, s, for the reception of a driving-chain, which connects with a pulley, u, on a shaft, fo, which also supports at'riction-disk, fw, engaging with go a wheel, a', on the axle 'u' of a car. The disk w is thrown into and out of contact with the wheel a by a bell-crank lever, c', attached to the bolster or frame of the car or truck.

The disk r and., its seat (j may be made of chilled cast-iron t`o. increase their durability. By putting the disl; w into engagement with the wheel a on the axle b the motion of the car is employed to operate the friction-disk o' and generate heat, which is transmitted to the roo water in the lower seetion,c,of the circulatingreservoir A7 and maintains the heat and circulation of the water when the train is in motion.

The friction-heater may be run by a separate motor or any other suitable means, as I do not limit my invention to any specific means of operation.

To provide for maintaining the heat of the water when the train is not in motion, fire may be made in the furnace i.

The reservoir A and all of the pipes and chambers G may be filled with hot water at a temperature of about 212 at stations along the road,ii` desired; or the water may be heated to about the same degree in the reservoir While the train is being made up preparatory to starting on a trip.

In applying the heater to a car the fire-pot or furnace is below the floor, and all of that portion below the floor, including the operating mechanism for the friction-heater, should be incased in sheet metal, while the upper portion of the circulating-reservoir throws oft' the heat of the water by radiation into the car.

In practice the temperature of the water will be maintained at about 150", which7 by the use of the foot-warmers for passengers to place their feet upon, will be sufficient to keep the car at a comfortable temperature.

Having thus fully described my invention, what I claim isl. A car-heater provided with an upper and lower water-chamber and a side passage connecting said chambers, in combination with an intermediate chamber communicating With the upper part of the upper chamber, and with a system of heating-pipes provided with a series of hollow connected flat mats or foot-warmers arranged on the floor of a car, substantially as described.

2. A oar heater provided with upper and lower connected water-chambers, a re flue or iiues passing through the upper chamber, and a furnace. in the lower chamber communieating with the ues in the upper chamber, in combination with an intermediate Water-chamber connected with the upper part of the upper chamber, and a system of heating-pipes provided with a series of hollow connected footwarmers arranged on both sides of a car, and a return-pipe communicating with the lower section of the reservoir, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
